TrueVision HD camera switched to spca2082 and is no longer showing image

[Naveeddil]

Dear SuperMario, Thanks for you kind reply even after so many long waiting. I did the same Uninstall the SPCA2082 from Imaging in Device Manager.

Turned off the computer and Restored the BIOS successfully

upon restart Device Manager had HP Truevision but as i launched WIndows 8 Builtin Camera App it immediately turned back into SPCA2082 and not showing any video in App.

Having the same issue, tried everthing listed on this forum, SPCA2082 comes back, and truevision HD built in camera does not work at all. It blinks, seems to start, but it shuts down very quickly. 

HP PPS HW team, please do something,

Tks.

All,

Welcome to the HP Forum.

Commentary

It is this Expert's opinion that this is not an "HP" only issue.

For any of you who have tried to track down a fix for the issue, you must notice that the problem has been seen on a variety of computers from different manufacturers.  The problem has been around for while, too.

It might be that at some point, a magic bean will be found that fixes the issue for everyone - and the magic may indeed come from HP's resources.

• The issue may be hardware inspired - a partial collapse of the webcam components are sending mixed signals to the software that cannot be correctly interpreted.

• The issue may be a corruption, version issue, or compatibility problem in the underlying Windows driver system - perhaps in the generic Microsoft USB Video Device driver.

Example from working system (Envy dv7t TS) running Windows 8.1 Pro:

Device Manager > Imaging Devices > HP TrueVision HD > Properties > Driver > Driver Details

C:\Windows\System32\Drivers\ksthunk.sys

C:\Windows\System32\Drivers\usbvideo.sys

NOTE: 

The built-in webcam is a composite device - there are other drivers and components in addition to the ones shown here.

See mention of the Windows video driver and its role in the following documents:

Fixing Webcam After Changing the Operating System

USB Video Class Driver Overview  **

** Interesting and multi-faceted article

If the issue is software based, then you might be able to fix the issue, even if the problem is down in the Operating System itself.  For example, assuming you have all your personal files and programs backed up, you can issue a Refresh or Custom Refresh on a Windows 8 computer to overload the Operating System.

If the issue is hardware based, that is, one or more components are failing, resetting, or in some way misbehaving, then you can change all the software and BIOS - and the webcam will still be broken.

My point is simply that while HP computers are occasionally affected by the issue, it is not an HP-only problem.

Thank you for the responses. Based on my research, a clean install of Windows should eliminate the issue. I'm referring to removing the operating system completely, then installing a fresh version. For more information on how to do this, please reference this Microsoft website: Installing and reinstalling Windows

Please let me know if you have any other questions or concerns.

Mario,

I agree that the users afflicted with the problem should try an install of the OS - the trick is to get someone to try it.  Smiling.

No one wants to reinstall their OS - reinstalling involves both risk and a bit of work.  If the user has a nice, clean Image available then it might be less scary.

The issue is wide spread, not new, and apparently not well understood.

[SuperMario1]

Dragon-Fur,

Yes, it is true that the issue is wide spread. I've forced myself to put a good hour of research in the issue, since it slightly confused me. I do agree that the trick is actually performing a reinstall of Windows.

The other solution I was thinking was to reinstall the Chipset drivers. Once reinstalled, installing the correct drivers to address the camera may be successful. Just a thought, because it seems like the essential driver is being overridden.

Alternatively, uninstalling all the related drivers, then immediately perform Windows Updates. Once the updates are complete, reinstalling the drivers might be successful.

One other thing that came up in research was the possibility of a virus. There are certain viruses that enable activity similar to this.

Of course, this is all speculation and theory. Until more troubleshooting is done, the true answer won't be known. Perhaps that is what makes issues like this so interesting.

Actually, I've done this. I did a fresh install of Windows 8, partitioned it, installed Ubuntu Linux on the second partition, and then upgraded to 8.1. It still gave me the same problems.

nhalloway,

This webcam is a SunPlus device and it is used by several manufacturers, including (but not limited to): 

HP, Asus, Acer, Lenovo, Rapoo (gaming mice), and other "smart" mouse makers.

The generic drivers and other relevant information are listed at the awdit website.

According to the data, this composite device is interdependent on several drivers, including:

 usbccgp ‐ USB Common Class Generic Parent Driver

6.3.9471.0.30.130726.2004            usbccgp.sys                        July 27, 2013

6.3.9431.0.130615.1214                  usb.inf, usbccgp.sys        June 16, 2013

  usbvideo ‐ USB Video Class Driver

6.3.9431.0.130615.1214                  usbvideo.inf, usbvideo.sys          June 16, 2013

6.3.9369.0.14.130324.1300            usbvideo.inf, usbvideo.sys          March 25, 2013

Reference: 

Microsoft-provided USB drivers

If you are sure the hardware is functional -- and this is a leap, I know -- then the issue tracks back to the generic Microsoft drivers. 

This is a composite device: everything must be updated to a certain level (or beyond?) and every part of the management of the drivers must be realized (possible) without issue.  That means that if you installed, for example, Update 2862330 and it resulted in system errors, then a key part of the update that might include usbccpg.sys may have failed.  The fix for that particular issue is to remove patch 2862330 and try reinstalling it.    Reference:  MS13-081: Description of the security update for USB drivers: October 8, 2013

Having Linux on the system MIGHT be complicating things.

JUST understanding the one driver, usbccgp.sys, may take some time - once understood, you might judge better if this driver is failing to provide service.  For example:  the device may fail if the power request sent to the device does not match the available resource - the device needs more power than what the USB port can deliver.  Remember, this is an example only.  Power delivery is likely not the issue unless 1) the hardware is faulty (unproven), 2) the driver assemblies are at fault (unlikely).

Someone with a better understanding of the technology should persue this; my own skillset in this area is limited.

In short, my limited understanding of the root cause hampers me.

My advice includes the following:

• Make sure every USB port driver is up to date - check the FileRepository in DriverStore to assure your system is not harboring an old driver
  
• Check the Event Viewer to assure there are not hardware errors or even warnings related to this issue (think composite)
  
• Make sure your Mouse software is up to date (yes, touchpad)
  
• In an extreme example, I would suggest that Linux is in part to blame -- NOT evil, but perhaps meddling with the kernel.   You might remove your Ubuntu install temporarily.
  
• Update or remove Skype and then use a Hard Reset to get the last bits of Skype out of the system.  This is intended as a temporary diagnositc;  assuming the webcam is again stable at some point, Skype (newest?) could be reinstalled.
  

• As a secondary test:  Remove Ubuntu and replace it with Mint..  Susa 13.1 is good, too.
  

Go get 'em Mario!

So, just to be certain: how can I be 100% positive that the hardware works? And then when I make that determination that it isn't a hardware fault, how do I determine what patch it is that's causing the software issue?

And naturally, I can uninstall Ubuntu and install OpenSUSE or something if the above don't work.

[Dragon-Fur]

nhalloway,

I do not know the magic answer about the hardware -- if ALL else fails to correct the issue, then one must suspect that some part of the hardware is faulty.  Computers are just boxes full of bits that do certain things when all goes well.

A qualified hardware technician might be able to check voltages, connections, and functional camera responses.

As to the drivers, you have to locate them, check the properties, and then the driver revisions.  IF the issue is within a driver update / version / mismatch, then it may be deep in the OS.   There may have been an Update applied in Windows Updates that somehow caused the issue.

The only reason I tapped the Linux chord is that in Linux there is a relationship between a driver handling spca2082 and a working webcam.  It may be "magic beans", that is, without value on its own.

I am sorry that I could not help you enough to give you the answer you seek.  I not encountered the issue on any of my computers, I have not been able to find a definitive and clear answer based on what others have said.

To make it easier to track down and look at the drivers on your system, you can use this tool: 

DriverView v1.45 - Loaded Windows Drivers List

I have this installed on Windows 8.1 Pro and I have used it previously on Windows 8 and Windows 7 machines.
